Schluter DITRA30M is a uncoupling membrane that protects tile and stone coverings from the effects of substrate movement and moisture. It's made of a polyethylene material with a grid structure of square cavities. The anchoring fleece on the underside of the membrane is embedded in thin-set mortar to provide a mechanical bond to the substrate. Ideal for use in areas with high moisture or substrate movement, such as bathrooms, kitchens, and mudrooms, it can be used over a variety of substrates, including concrete, plywood, and OSB. Some of the benefits of using Schluter DITRA30M include:

Uncoupling: Protects tile and stone coverings from the effects of substrate movement.

Uncoupling: Protects tile and stone coverings from the effects of substrate movement.

INNOVATIVE SOLUTIONS FOR CERAMIC AND STONE TILE

Ceramic and stone tiles are durable, easy

to maintain, and hygienic, representing

the ideal surface coverings. However,

today’s lightweight construction

methods can make the installation of

hard surface coverings particularly

challenging. In order to protect the

integrity of the tile assembly, an

underlayment that performs multiple

functions is required.

Application and Function

6.1 Schluter

-DITRA and 6.1 Schluter

DITRA-XL are polyethylene membranes with

a grid structure of square cavities, each cut

back in a dovetail configuration, and an

anchoring fleece laminated to the underside.

The anchoring fleece is embedded in thin-

set mortar to provide a mechanical bond to

the substrate. Tile is installed over DITRA or

DITRA-XL using the thin-bed method in such

a way that the mortar becomes mechanically

anchored in the square, cutback cavities of

the matting.

Designed specifically for ceramic tile

and dimension stone installations,

DITRA and DITRA-XL serve as an

uncoupling layer, waterproofing

membrane, and vapor management

layer that accommodates moisture

from beneath the tile covering. Further,

DITRA and DITRA-XL perform all these

functions while still providing adequate

support/load distribution for the tile

covering. The combination of these

four essential functions allows for the

successful installation of tile over a wide

range of substrates, including plywood/ OSB,

concrete, gypsum, heated floors, etc.

DITRA is 1/8" (3 mm) thick, which

minimizes tile assembly thickness and

reduces transitions to lower surface

coverings (e.g., carpet, engineered wood,

and vinyl). DITRA allows for ceramic tile

application over single-layer plywood or

OSB subfloors on joists spaced up to

19.2" (488 mm) o.c. DITRA-XL is 5/16"

(7 mm) thick, which permits even

transitions between tile and 3/4"-thick

hardwood flooring. DITRA-XL allows for

ceramic tile application over single-layer

plywood or OSB subfloors on joists spaced

up to 24" (610 mm) o.c.

Uncoupling

Tile has been successfully installed for

thousands of years by incorporating

an uncoupling layer, or forgiving shear

interface, within the tile assembly.

DITRA and DITRA-XL provide uncoupling

through its open rib structure, which allows for

in-plane movement that effectively neutralizes

the differential movement stresses between

the substrate and the tile, thus eliminating the

major cause of cracking and delaminating of

the tiled surface.

Waterproofing

DITRA and DITRA-XL provide reliable

waterproofing in interior and exterior

applications. Its polyethylene composition

protects the substrate from moisture

penetration, which is particularly important

in today’s building environment where most

substrates are moisture-sensitive.

Vapor management

The distinguishing feature of DITRA and DITRA-

XL is the existence of free space created by the

configured channels on the underside of the

matting. The free space provides a route for

excess moisture and vapor to escape from the

substrate that could otherwise cause damage

to the tile layer above. Thus, DITRA and DITRA-

XL effectively manages moisture beneath the

tile covering.

Support/load distribution

When placed on a solid foundation,

columns or pillars can support tremendous

loads. The same physical principle applies

to DITRA and DITRA-XL installations.

Column-like mortar structures are formed

in the cutback cavities of the matting.

Loads are transferred from the tile covering

through these column-like mortar structures

to the substrate. Since the matting is

virtually incompressible within the tile

assembly, the advantages of uncoupling

are achieved without sacrificing point load

distribution capabilities. The ability of DITRA

and DITRA-XL installations to support and

distribute heavy loads while preserving the

integrity of the tiled surface has been verified

through extensive laboratory and field testing,

including applications exposed to vehicular

traffic.

Material Properties and

Areas of Application

DITRA and DITRA-XL are manufactured using

high-density polyethylene (HDPE), which

does not rot and is inert, non-toxic, and

physiologically safe. The material is highly

resistant to solutions containing salts, acids,

and alkalis, as well as many organic solvents,

alcohols, and oils. Resistance to specific

stresses can be provided if concentration,

temperature, and exposure time are known.

DITRA and DITRA-XL are waterproof and

minimize the transmission of vapor (water

vapor permeance of DITRA is 0.006 perms

per ASTM E96).

DITRA and DITRA-XL meet the American

National Standard for Load Bearing,

Bonded, Waterproof Membranes for Thin-

Set Ceramic Tile and Dimension Stone

Installations (ANSI A118.10), are listed by

cUPC®, and are evaluated by ICC-ES (see

Report Nos. ESR-2467 and PMG-1204).

DITRA and DITRA-XL were evaluated

according to the "Standard Method for the

Testing and Evaluation of Volatile Organic

Chemical Emissions from Indoor Sources

Using Environmental Chambers, Version

1.1" for California Specification 01350 and

found to comply with the VOC requirements.

California Specification 01350 is referenced

by various green building standards and

rating systems.

Note: Due to air space within the assembly,

tile coverings installed over DITRA or DITRA-

XL may have a hollow sound when they are

walked upon with hard shoes or tapped with

a hard object.

All

substrates must

be clean, even, and load

bearing. Bond-inhibiting surfaces must be

removed prior to the application of DITRA

and DITRA-XL.

Note: Type, thickness, and format of the tile

or stone surface covering must be suitable

for the intended application. Minimum tile

format is 2" x 2" (5 x 5 cm).

Wood

All wood materials, including OSB, plywood,

and framing members, are subject to

expansion, contraction, bending, and deflection

as a result of changes in moisture content

and loading. Further, these deformations

fluctuate over the life of the building structure.

DITRA and DITRA-XL’s uncoupling

function protects the ceramic or stone

tile covering from the aforementioned

deformations by neutralizing the differential

movement stresses between the wood

structure and the tile, thus eliminating the

major cause of cracking and delaminating

of the tiled surface. Therefore, DITRA

and DITRA-XL can replace a second layer

of plywood in most applications. Since

the uncoupling function of the matting is

based on its geometric configuration, the

increased thickness of DITRA-XL results in

increased uncoupling capacity. Thus, DITRA-

XL is optimized for tile installation over

bending and deflecting substrates such as

plywood and OSB, including applications

over single-layer plywood/OSB subfloors on

joists spaced at 24" (610 mm) o.c.

Wood continually absorbs and releases

moisture. The free space beneath

DITRA and DITRA-XL allows the wood

to breathe and provides a route for any

residual moisture in the wood substrate

to escape.

Since DITRA and DITRA-XL is virtually

incompressible within the tile assembly,

the advantages of uncoupling are

achieved without sacrificing point load

distribution capabilities.

substrates include methods F147 and F148

in the TCNA Handbook for Ceramic, Glass

and Stone Tile Installation and method 313F

Association of Canada (TTMAC) Specification

Guide 09 30 00 Tile Installation Manual.

Note: DITRA and DITRA-XL may be installed

over existing vinyl floors (no cushioned or

perimeter bonded vinyl). However, various

steps must be taken to ensure a successful

installation. Please refer to the Schluter

-DITRA

Installation Handbook for details.

Concrete

There are various challenges associated with

the installation of hard surface coverings on

concrete substrates. To begin, the coefficient

of thermal expansion of concrete is close

to twice that of ceramic tile. Additionally,

tile contractors are often expected to install

tile over young concrete (concrete cured

less than 28 days). However, rigid surface

coverings installed over young concrete

are susceptible to damage as a result of

shrinkage during curing. Pre-stressed/

post-tensioned concrete slabs are also

UNCOUPLING MEMBRANES

commonplace in today’s construction

environment. Although pre-stressing is

used to help control deflections in concrete

structures, these slabs are still subject to

deformations caused by changes in

moisture, temperature, and loading. Many

concrete slabs on or below grade are

subject to moisture migration, which can

be problematic. Furthermore, these

structures experience the same

deformations as stated above.

DITRA and DITRA-XL’s uncoupling function

protects the ceramic or stone tile covering

by neutralizing the differential movement

stresses between the concrete substrate

and the tile, thus eliminating the major cause

of cracking and delaminating of the tiled

surface.

DITRA and DITRA-XL’s waterproofing ability

not only protects the substrate from moisture

and harmful substances, it also slows the

drying of fresh concrete, thus reducing the

chances of cracking and curling.

The free space beneath the DITRA and DITRA-

XL matting provides a route for any residual

moisture in the concrete slab to escape. This

allows the installation of DITRA and DITRA-

XL and the tile covering as soon as the slab

can be walked upon. Vapor management is

also essential for slabs subject to moisture

migration.

Since DITRA and DITRA-XL is virtually

incompressible within the tile assembly,

the advantages of uncoupling are achieved

without sacrificing point load distribution

capabilities. This allows DITRA and

DITRA-XL to be installed in commercial and

industrial applications exposed to heavy

vehicular traffic, provided the type, format,

and thickness of the tile are appropriate for

the application.

D) in the Terrazzo, Tile and Marble Association

09 30 00 Tile Installation Manual.

Gypsum

Bonding ceramic or stone tiles directly

to gypsum concrete substrates is

generally considered questionable or not

recommended. The challenges associated

with gypsum-based underlayments include

the requirement of an extended drying period

before installing tile and continued sensitivity

to the reintroduction of moisture throughout

the life of the installation. In addition, since

the coefficient of thermal expansion of

gypsum concrete is substantially greater

than that of ceramic tile, shear stresses

caused by temperature fluctuations can

result in delamination or cracking of the

tile covering. This is particularly important

when gypsum concrete is used as a

thermal mass for radiant heated floors.

With the increasing popularity of radiant

heated floors, which typically utilize gypsum

concrete, tile installers need a reliable

installation system to address these issues.

DITRA and DITRA-XL’s uncoupling function

protects the ceramic or stone tile covering

by neutralizing the differential movement

stresses between the gypsum concrete

substrate and the tile, thus eliminating the

major cause of cracking and delaminating of

the tiled surface.

DITRA and DITRA-XL’s waterproofing

function prevents the reintroduction of

moisture to gypsum concrete underlayments,

which, if not prevented, could significantly

compromise performance of the

underlayment and lead to damage of the

tiled surface. The residual moisture in

gypsum concrete is allowed to escape

through the air channels on the underside

of the matting. This is particularly important

since gypsum concrete must dry in order to

gain strength.

Since DITRA and DITRA-XL is virtually

incompressible within the tile assembly,

the advantages of uncoupling are achieved

without sacrificing point load distribution

capabilities.

Installation Manual.

Heated Floors

Radiant heating is one of the fastest

growing market segments in the

construction industry. Unlike other surface

coverings, the low thermal resistivity of

ceramic and stone tiles allows them to be

used in radiant heat applications without

sacrificing the energy efficiency of the

system. However, there are inherent

challenges in combining rigid surface

coverings with radiant panel heating systems.

A viable installation system must address

the magnified fluctuations in temperature

that contribute to increased shear stresses

between the heated assembly and the

tile covering. The system must also limit

thermal striping by promoting even heat

distribution and protect the assembly from

moisture, which is particularly important

when gypsum concrete is used as the

thermal mass. Differential movement

stresses are magnified in radiant-heated

floor applications because of significant

temperature gradients.

DITRA and DITRA-XL’s uncoupling function

protects the ceramic or stone tile covering

by neutralizing the differential movement

stresses between the heated assembly and

the tile, thus eliminating the major cause

of cracking and delaminating of the tiled

surface.

DITRA and DITRA-XL’s waterproofing function

provides simple, effective, and permanent

protection for moisture-sensitive substrates,

such as gypsum concrete and wood, used in

heated floor applications.

The open rib structure of the DITRA and

DITRA-XL matting allows the residual

moisture in the substrate to escape.

This is particularly important for gypsum

concrete since it must dry in order to

gain strength. In addition, the free space

beneath the matting limits thermal striping

by promoting even heat distribution

throughout the assembly.

Exterior Applications

Ceramic and stone tiles are ideal surface

coverings for the exterior and have been used

successfully for thousands of years. Exterior

balconies and terraces are ideal opportunities

for the installation of tiled surfaces. However,

these installations have typically presented

significant challenges to tile setters. Since

hard surface coverings are rigid by nature

and have different physical properties

compared to virtually every substrate, they

cannot be bonded directly to the substrate,

particularly in exterior applications where they

are exposed to potentially severe climatic

changes and the recurring introduction of

moisture.

DITRA and DITRA-XL’s uncoupling function

protects the ceramic or stone tile covering

by neutralizing the differential movement

stresses between the substrate and the tile,

UNCOUPLING MEMBRANES

thus eliminating the major cause of cracking

and delaminating of the tiled surface. This

is particularly important since these stresses

are magnified by the significant temperature

gradients common in exterior applications.

DITRA and DITRA-XL provides effective

waterproofing that will protect the tile

assembly from the recurring introduction

of water which is common in exterior

applications.

The free space beneath the

DITRA and

DITRA-XL matting provides a route for any

residual moisture in the substrate to escape.

This is especially important when installing tile

over a young slab, a concrete slab subject

to moisture migration, or a fresh mortar bed.

Since DITRA and DITRA-XL is virtually

incompressible within the tile assembly,

the advantages of uncoupling are achieved

without sacrificing point load distribution

capabilities.

Thin-set Facts

Schluter

-Systems offers thin-set mortars

designed for use with Schluter

membranes

and boards. All Schluter

-Systems’ thin-set

mortars, including the ALL-SET™ and FAST-

SET™ modified varieties, can be used to

set tile over Schluter

-DITRA, DITRA-HEAT,

KERDI, KERDI-BOARD, etc. non absorptive

substrates. If Schluter

thin-set mortars are

not used, we require unmodified thin-set

mortar when setting ceramic or porcelain tile

over DITRA-HEAT.

Question: Can ceramic tile, including

porcelain tile, be set on DITRA with

unmodified thin-set mortar?

Answer: YES. In fact, we recommend it.

Here’s why: Portland cement-based

unmodified thin-set mortars are dependent

on the presence of moisture for hydration

in order to gain strength. Since DITRA is

impervious, it does not deprive the mortar

of its moisture. This allows the cement to

properly hydrate, resulting in a strong, dense

bond coat. In fact, after the mortar has

reached final set (usually within 24 hours),

unmodified thin-set mortars achieve higher

strengths when cured in continually moist

conditions.

Question: Can ceramic tile, including

porcelain tile, be set on DITRA with latex-

modified thin-set mortar?

Answer: In general, we DON’T recommend it.

Here’s why: Latex-modified mortars must

dry for the polymers to coalesce and form

a hard film in order to gain strength. When

sandwiched between two impervious

materials such as DITRA and ceramic tile,

including porcelain tile, drying takes place

very slowly through the open joints in the tile

covering. [According to the TCNA Handbook

for Ceramic, Glass, and Stone Tile Installation,

this drying period can fluctuate from 14

days to over 60 days, depending on the

geographic location, the climatic conditions,

and whether the installation is interior or

exterior]. Therefore, extended cure times

could be required before grouting if using

modified thin-set mortars between DITRA

and ceramic tile, including porcelain tile. If

extended cure times were not observed,

the results could be unpredictable. This is

even more important to consider in exterior

applications that are exposed to rain as there

is the additional concern of latex leaching.

Question: Can Schluter

-ALL-SET and

Schluter

-FAST-SET modified thin-set

mortars be used to set tile over Schluter

boards and membranes?

Answer: Yes. All Schluter

thin-set mortars,

including the ALL-SET and FAST-SET

modified varieties can be used to set tile

over DITRA, DITRA-HEAT, KERDI, KERDI-

BOARD, etc. non absorptive substrates.

Question: How is this possible?

Answer: The key is predictability. Schluter

Systems’ modified thin-set mortars have

been specifically formulated to set and

gain strength in a timeframe that fits typical

installation practice, even when sandwiched

between Schluter

membranes or boards

and porcelain tile. The proportions of

cement, water-retention agents, polymers,

and other components in the mixtures were

balanced to ensure that extended dry times

are not required. This was validated through

both laboratory and practical testing. Now,

the installer can select from either unmodified

or modified thin-set mortar to install tiles

within our systems according to his or her

preference.

Question: Why did Schluter Systems change

its position on thin-set mortar?

Answer: We haven’t changed our position

on thin-set mortar use within our systems.

Developing our own setting materials has

given us the ability to guarantee consistently

positive results. And since we control the

formulas, we can be sure no changes will

be made that have a negative impact on

setting times and strength gain in these

environments.

Question: Does this mean I can use other

manufacturers’ modified thin-set mortars

to install tile over Schluter boards and

membranes?

Answer: No. Our position on thin-set mortar

use within our systems in general has not

changed. We have no control over the

formulation of other manufacturers’ products

and therefore cannot guarantee consistently

positive results with their modified thin-set

mortars.

Question: Can I still use other manufacturers’

unmodified thin-set mortars to install tile over

Schluter boards and membranes?

Answer: Yes. We still warrant the use

of unmodified thin-set mortar meeting

ANSI A118.1 to install tile within our

systems because we have confidence in

the performance of this product category.

This is based on the science of cement

hydration and years of positive testing and

field experience.

Please note, if Schluter

thin-set mortars are

used with Schluter membranes an extended

system warranty is available.

Additional Notes:

Remember, the type of mortar

used to apply DITRA or

DITRA-XL depends on the type of

substrate. The mortar must bond to the

substrate and mechanically anchor the

fleece on the underside of the matting.

For example, bonding DITRA and DITRA-

XL to wood requires latex-modified thin-set

mortar. Additionally, all mortars (modified and

unmodified) have an acceptable temperature

range that must be observed during

application and curing.

Movement Joints

DITRA and DITRA-XL do not eliminate the

need for movement joints, including perimeter

joints, within the tiled surface. Please refer to

the Schluter

-DITRA Installation Handbook

for movement joint placement guidelines.

UNCOUPLING MEMBRANES

Wood Underlayment

In some applications, adding a layer of plywood

or OSB before installing DITRA or DITRA-XL

and the ceramic or stone tile covering is

required to reduce deflection and curvature

of the sheathing between the joists. Please

refer to the Schluter

-DITRA Installation

Handbook for plywood/OSB underlayment

installation guidelines.

Exterior Installations

It is recommended that DITRA and

DITRA-XL be allowed to adapt to ambient

air temperature before installing. Further, if

low temperatures are expected during

installation, proper care to ensure sufficient

strength gain of the thin-set mortar must

be taken.

Connection to Floor Drains

Schluter

-KERDI-DRAIN or Schluter

KERDI-LINE may be used to provide

drainage in DITRA or DITRA-XL applications.

DITRA or DITRA-XL are sealed to the fleece-

laminated KERDI-DRAIN bonding flange with

a section of KERDI membrane using Schluter

SET™, Schluter ALL-SET™, Schluter FAST-

-DITRA-XL (the “Products”) will meet all composition and performance criteria for a period of ten (10) years from the date of purchase only when the

Products are used and installed in accordance with the terms and conditions of the Schluter

-DITRA Installation Handbook and industry standard guidelines

that are not in conflict with the Handbook in effect at the time of installation. Further, efflorescence is considered to be a natural occurrence with cementitious

materials and is therefore not considered to be a defective condition and is not covered by this warranty. It is the responsibility of the owner/ builder/ installer

to ensure the suitability of all building materials and all associated building materials for the owner’s intended use. It is recommended that the owner consult

with an experienced and professional installer.

RESOLUTION: If the Products fail to meet this warranty, then the owner’s exclusive remedy and the sole obligation of Schluter-Systems, at its election,

shall be to a) reinstall or replace the failed portion of the floor covering assembly or b) pay an amount not to exceed the original square foot cost of

the installation of the floor covering assembly verified to be defective. Floor covering assembly is defined to include all DITRA or DITRA-XL materials,

non-reusable flooring surfaces, and the appropriate setting and grouting materials. Further, due to conditions beyond the control of Schluter-Systems (e.g.,

color and shade availability, discontinuation, normal wear and tear), Schluter-Systems cannot guarantee or warrant an exact match to the specific tile, stone,

or other flooring materials used in the installation. In such events, substantially similar materials may be substituted.
